Cutting Gears on Two MechMates! #38 & #130 - Parnu, Estonia

[Jason Marsha]

Wow. No lubricant?

[ifffff]

Yepp, no lubricant. On shown settings is tool lifetime somewhere between 50-100 cutting hours. I have cut over years tens of tons alu sheets so. Maybe with emulsion it is longer, but i try avoid lubricants. Too messy

[YANLM]

it's very impressive, nice job. have you a link for the one flute endmill?

[ifffff]

Well... They are coming from Estonian reseller with product code what does not lead nohere and here have they EcoStar trademark. Again google isnt sayng nothing.

Sometimes they have engraved Cerin on them and i quess they are 110A.050051450 http://www.cerin.it/catalogue.pdf Page 150

My quote to Cerin had answer that go and buy from your local reseller, so ... propablly they are that ones.

[YANLM]

ok thks i will take a look.

Made some rope driven blast gates. I think they are better than regular push-pull type gates.

I have here some kind of strange problem here with my new MM.
X axis gear is totally worn and gear rack looks worse than my 9 year old #38 gear racks. A and Y axis gear/racks are looking as new. All of them are from same source. Nothing does not seem to be misaligned .... Does anyone have idea what may cause it??

Wooow....can't confirm & no "metal" guru.....
But....say, in my case it was a question of how "tight" or say, how strong is the spring tension "up pulling" the motor to rack ?!
Surly you have check this & fully aware of this, but, sometimes I too tend to oversee the most "obvious"...

Best of luck...

[jask]

I would contact the original manufacturer, the alignment and count look good and that makes me think the gear was not properly hardened.

[ifffff]

All three axis have same spring and tensioned equally. And weared is only one gear, so reason cant be over tensioned spring.
I will ask what is answers have gear/rack seller.

[Regnar]

If I had to guess and this is only speculation I think your gear did not go through a hardening process after it was machined. It became the weakest link and wore out first. You can run a file over it and see how much metal it removes compared to your other gears.

[ifffff]

Ok i will try how much it is softer. But all gears what i have used on both mechmates arent hardened. On #38 is gear lifetime 2-3 years hard work.

I made sprocket milling video

[YANLM]
